Well why the hell not? if animals do it, then surely it must be natural......
Animals don't have social rules or expectations to adhere to though do they?
The argument that homosexuality is natural because animals do it holds up because it is merely showing that it is not a concious choice, and it is something that alot more species have, but this by no means says that rape and cannibalism are acceptable because by our social rules and expectations, regardless of whether these are natural or not (which technically they are), they're morally wrong for a modern society.
People aren't denying rape and cannibalism are natural for animals, because like I said, technically they are, but they dont fit in a modern day society, and in essence, the fact that rape and cannibalism are natural means homosexuality is also natural, which can fit perfectly well into a modern day society, as demonstrated by the Western World in general.
Because something is consensual it doesn't make it right or moral. Incestous sex can be perfectly consensual but that does make it right. And if you argue that it is, then there is something really wrong with you.
Incestual sex can have bad consequences though, homosexuality cannot (relatively, ofcourse you can contract STD's etc but they come with straight sex aswell), so once you've agreed that both are consensual, you have to look at them and work out if they're detrimental. One could also argue that if incestual sex is done with the consent of two parties, is in a private residence and appropriate contraception is used, it has no detrimental effect on society.
And no, there is nothing "really wrong" with me for saying that, and i'm merely pointing out that under certain circumstances incestual sex could be acceptable. Another view is that the state shouldn't play a role in what we do in the bedroom, so if it is consensual and done responsibly, and doesn't break the law (ruling out rape and cannibalism) it isn't the state's business to decide what we can and can't do, just saying.
